Starker fuck or die

This is insane. The entire day has been one dumpster fire after another. Peter fell asleep on top of a building still in costume with his textbook spread open on his lap to the sound of a phone call. The resulting jolt of unfortunate awareness nearly sent his school books down onto the pavement — instead they just have a stain from the webbing and an extremely damaged spine. Peter answered the phone but was more interested in mourning his rental deposit than whatever threat was causing the Avengers to assemble. 

Then he heard the words Sex Demon come out of Captain America’s mouth and it was all downhill from there. Forlorn, Peter agreed to set his studying aside and come help out, because, really, when was he going to have another opportunity to sit in a room while Steve Rogers tried to talk about a Sex Demon in the debrief? 

It wasn’t nearly as fun as Peter expected. They’d called him in because he was difficult to hit and had the benefit of both long- and short-range fighting, but some of the others weren’t so lucky. By the time he arrived, Black Widow had already been removed by Hawkeye, leaving Second Hawkeye looking very purple (“nice new uniform, Kate!”) and incredibly perplexed. Steve was mostly alright, but whatever was causing problems was not reacting well to the serum.

Causing problems, of course, meant making people extremely Down to Fuck extremely quickly. 

“This is hilarious,” Peter says, swinging around the rafters. The warehouse they’re in has already been trashed, light leaking in through the roof and scaffolding collapsed in heaps on the concrete floor. “There is so much porn about this. At least two. Not that I know for sure.”

Tony comes over the comm. “I did hear Sex Pollen Sluts Go Nuts got excellent reviews.”

No one thinks this is funny at all, but Peter is too busy twisting out of harm’s way to feel bad about laughing. 

It’s not a Sex Demon, which Peter finds incredibly disappointing. It’s just a man who believes in the power of the aphrodisiac, or something, and developed yadda yadda whatever he’s trying to get blackmail of the world’s most influential people blah blah super awkward and gross and his sex blaster doesn’t even look cool at all. 

None of this is the particularly insane part.

The insane part happens about two seconds after Tony manages to topple Mr. Sex Demon over the railing and onto the ground, where the pressurized canisters on his back give way to the unforgiving asphalt and explode into a green haze so dense Peter can barely see the brilliant blue glow of the arc reactor in Tony’s chest.

“Mr. Stark!” Peter yells into the comm, without a response, and he’s swinging over to assess the damage when Captain barks orders for him to stay out of the way.

The Iron Man suit is already vacuuming up the fumes to remove the contaminant from the air, but Tony hadn’t been wearing one of his space safe suits which means there’s no internal oxygen supply, which means he’s also been contaminated. Regardless, the two men come into view and Tony just waves. “FRIDAY gives the all clear.” His voice sounds strained.

Peter drops down just behind. “Mr. Stark!”

“Spider-Man,” Steve calls, jogging over. “It’s best not to get to close—”

Peter is about to ask what Steve could possibly mean when he feels heavy hands grip his shoulders. The Iron Man gauntlets are heavy — in the armor Tony weighs nearly 400 pounds — and Peter winces. “Mr. Stark?” 

He isn’t afraid — Natasha hadn’t been dangerous. She’d stood stock still for a moment, called for assistance, and immediately removed herself. Over the phone, Captain America had run through the symptoms of the spores, but Peter can’t remember all of that now. He vaguely remembers a loss of inhibition, some kind of animalistic behavior, and an increase in body temperature to dangerous levels over time.

“Tony,” Steve says warningly. 

Iron Man’s faceplate lifts up and Tony is sweating, gritting his teeth. “I know, Cap.” His hands tighten, shaking, enough that Peter grabs one and flexes his fingers, debating whether to pry it off. “I’m trying.” Deep breath.

“Get away from the kid, Tony.” Steve pulls out his firearm and Peter is about to laugh, it’s insane, Tony would never hurt him. Touching Peter isn’t something Tony isn’t allowed to do. But when Peter goes to laugh Tony still looks so serious, so stony, almost sick. Deranged, even. Just a little.

“Mr. Stark?” Peter frowns and Tony’s eyes flutter closed, tight.

“Don’t call me that, right now, kid.”

Kate hops down from her perch in the rafters, awkwardly adjusting the quiver on her back. “I’m just gonna, uh, go.” She gestures over her shoulder to the door, which Tony blasted off the hinges not half an hour ago. “I’ll find a broom or something. Or just leave.”

Steve nods, mouth tight. His gaze doesn’t leave Tony where he’s hunched over Peter like a bad shadow, but his finger stays still on the trigger. Waiting. Not moving one way or the other.

Peter knows how these sorts of things go; if something can go wrong, it will. He runs through the data he can grapes through the confusion, tapping into Tony’s suit. Tony had been exposed to nearly twenty times the recommended dosage. Peter pulls his vitals through Karen and tries not to balk at Tony’s heart rate or internal temperature. Hot. Tony could fry an egg on his chest soon. “We need to get you out of the suit.” Peter reaches for one of the latches.

“Leave it,” Tony grunts. He’s bitten his lip so hard there’s blood in the corner of his mouth. “Better.” His hands haven’t moved, like he can’t move them, like he’s a statue. Peter is going anywhere without forcing himself free. “Better for you.”

“For me?” Peter demands. His hands are already on the gauntlet, but he freezes, struck silly by the sheer nerve. Tony is overloading and he thinks he should stay in the suit for Peter’s sake?

“I’m calling Fury.” Steve brings one hand up to his ear, gun still level. His eyes don’t leave Tony the entire time, even when he backs away slightly and starts to argue on the private channel.

Peter’s fingers tap a nervous rhythm on Tony’s armor. “Karen says you’re spiking really fast, sir,” he says at a whisper. This isn’t good for Tony’s heart, still weak, or his nervous system, which has been run ragged.

“I’m fine,” Tony chokes out through clenched teeth. His skin looks terribly gray, haggard, even. “I am really reliving some of my old glory days right now, but I’m fine.”

“Oh, yeah. Drugs.” Peter laughs nervously. Tony’s eyes are blown, the warm brown consumed by darkness, and his gaze is heavy on Peter. The gauntlet moves now, pulling up the hem of Peter’s mask until Peter feels metal against his pulse point. “Mr. Stark?”

Tony groans.

Peter is a good kid, but he’s not a saint. He’s seen the Tony Stark sex tapes, even the ones that Tony didn’t know were being recorded. He’d been through his own moral beratement when he opened it the first time, but he’d done it several times since because they’re something about Tony that Peter can’t get enough of. And Peter has heard that groan a million times. It’s not like his enemy just punched me into a wall groan, or his this meeting could have been an email groan. It’s the groan he makes when he opens someone up with his cock for the first time. The eyes rolling back, hips stuttering kind of groan.

Peter is suddenly very hard in his jock strap. Terrible. Terrible news.

Karen is a welcome distraction in the form of more terrible news. “Mr. Stark!” The vitals displaying on Peter’s HUD are approaching dangerous levels, especially for an older, unenhanced human. “Your heart rate. It’s crazy!” 

Tony is sweating, mouth open in the face of the rising temperatures, and Peter starts to frantically start prying at the mechanisms that hold the armor together. Tony makes no move to assist. “Leave it.”

“You’re in a metal can and you’re already over 100F,” Peter tells him, as if Tony didn’t know. “You’re going to—”

He doesn’t hear Steve barking at him to stop. It doesn't strike him that it’s a bad idea until it’s too late.

Peter manages to get his nails under the ridge of the chest plate and release it, pulling back, and then suddenly he’s falling. Tony has miraculously changed his mind about the suit and decided to abandon it entirely, stepping out and using the momentum of Peter’s scrambling until they both fall prone on the ground. There’s a poof of dust as they clatter onto the warehouse floor, tangled together.

Steve looks over at them sharply and is yelling orders Peter can’t quite hear because he is too busy trying to place the way Tony is smothering him with his body. Even through Peter’s suit he feels the heat radiating off of Tony’s skin, so sweaty he’s almost slick. He smells like hard work and expensive cologne. Peter is bewildered, and he puts his hands on Tony’s chest to push him away only to freeze when he feels Tony pull up mask and lick a thick line from his collar to his ear. 

“Mr. Stark, I don’t—” Tony gets a hand between them, pushing the release on Peter’s suit until it’s loose around his body and Peter turns his head to look at Steve. “Captain, I didn’t think it was supposed to be, ah, oh.” He shudders when Tony sucks Peter’s ear into his mouth. “Mr. Stark, please. We need to get you to medical.”

“No time,” Tony mumbles against Peter’s throat. He’s cupping Peter’s groin through the suit while the other hand pulls the mask off completely. “Want you bad. God, I can’t even think. Look at you.”

“Tony.” Steve takes the safety off, conversation over the communicator set aside, and gets closer. He doesn’t want to shoot. That much is obvious — if he was going to, he would have already done it. “I said get off the kid.”

“He’s mine, Capsicle,” Tony growls. He winds his hands around Peter’s back until their chest to chest, and Peter feel the rabbiting heartbeat until it’s hard to separate whose is whose. “Get your own!” There’s the tell-tale fire up of the propulser on Tony’s palm, and then there’s a stare down between Iron Man and Captain America with a shivering Spider-Man sandwiched between.

Steve looks away first.

Peter feels a bit wild, wide-eyed, confused. Flushed and hot and not attractive at all, but Tony is near-tearing the suit off of his body and Peter is so shocked he’s barely fighting it. Cold air hits his sweaty skin where Tony is pulling it down at the neck and it feels like an electric shock. “Mr. Stark, seriously. You need to—oh.” There’s a rough hand on his cock. “Oh, my god.”

Tony has both hands on Peter again, like he’s going to reach into Peter’s chest and start pulling him apart, but the Iron Man suit is in sentry mode now; Peter hears the thunk of the boots on the ground even as he’s writhing, trying to focus past the sound of his own insane breathing. He blinks and then there is red and gold staring down the barrel of Steve’s gun.

“Need you, kid,” Tony growls in his ear, pulling down the length of him through his underwear. This was not on Peter’s bingo card for the day. “Feel like I’ll die without you.”

Maybe you will, Peter thinks hysterically.

Steve could stop this, but the gun is slowly falling lower until it’s pointed at the concrete. “Peter,” he starts, “if you give me the word, I’ll remove him and take him to quarantine until we find a willing partner.”

“Partner?” The puzzle pieces are falling into place but there has to be another picture because the one in Peter’s head isn’t making any sense. “I thought this just made you horny!”

“It sure does,” Tony mutters. He doesn’t spare Peter’s underthings nearly the same respect as the suit, but he tears Peter’s t-shirt off at the neck and spreads it open like a child opening a Christmas present. Hands splay flat over sweaty skin, feeling Peter’s rapid breathing. “I’m going to ruin you, kid.” Like he can’t hear a single thing.

“I’m not—oh, god.” Tony is heavy on top of him and his cock is hard in his sweats, thick where it’s digging into Peter’s hip. Tony readjusts and grinds them together, hard enough that Peter scrambles for purchase against Tony’s back. “Cap, I don’t know what to do. What do I do?”

Tony rakes his nails down Peter’s bare chest, catching on Peter’s nipples with a satisfied smirk.

“What do you want to do?” Steve asks slowly.

Tony has such a high fever and his heart rate is dangerous and he looks at Peter and says, “you want to be a good boy for me, don’t you?” and Peter is so fucked. He’s both literally and figuratively fucked.

Like a flash of lightning, Peter remembers the call earlier: if Tony doesn’t come inside someone, he’ll overheat until he’s either cooked inside or dies from a heart attack. It had sounded kind of funny at the time, only half-paying attention.

Despite having a god among men standing not twenty feet away — oh, god, Captain America can totally see Peter’s boner right now — Tony doesn’t look away from Peter for a single moment if he can help it. Years of the revolving door love interests have made Tony extremely good with his hands. He’s often joked about it, about how good he is in bed, but Peter never actually thought he’d feel the way Tony smoothes hands over skin or bites bruises cherry red and it’s just a whole lot more than Peter expected to happen.

“I—I…oh, god.” Tony licks a line from Peter’s navel up to his chest and latches on to one of Peter’s nipples with his teeth. “I’m, I’m willing. I just—”

“Are you sure?” Steve says firmly, like Peter might be able to think straight with Tony all over him like every unfortunate wet dream he’s had since the seventh grade.

“If you don’t leave right now,” Tony says with a growl, “you’re going to get quite the show, Cap.” His eyes look clouded over, and he sits back heavy on Peter’s cock and just looks at the mess he’s made. Peter’s suit is hanging haphazardly around his hips and his shirt is ruined and his skin is bright pink. The cold wind through the holes in the walls brushes past, too cool on the spit-slick on Peter’s chest and he shudders.

“I’m okay,” Peter chants, and he lets himself reach out and touch for the first time. It’s tentative, fingertips across the scarring on Tony’s chest. “Like, what the fuck, but also I’ll be okay.”

If anyone understands that, it’s Steve, who is flushed almost as red as Peter and pivots. “I’ll guard the perimeter.”

With a grin, Tony rolls his hips so fluidly Peter whines high in his throat. “Kind of wanted to put on a show.” His cock is so hard, rutting into the dips of Peter’s stomach. “Bet he’ll watch. He just doesn’t want to admit how good you look. My perfect boy.” He grabs both sides of Peter’s head, fingers tangling in his hair so hard Peter can’t look anywhere but straight ahead.

Peter presses his hands flat. “Mr. Stark, I…” He closes his eyes tight. “What do I do? This is crazy.” Not last week Tony had been helping Peter with relationship advice, how to get a girl’s attention, clapped him on the shoulder and called him champ like he was going to take Peter to the baseball game later. “You’re…” 

The first time Tony kisses him, Peter’s brain doesn’t care about the drugged nature of it. It’s everything he wants, everything he thought it would be in his wildest dreams. It’s possessive, almost bruising, like Tony is boiling over and he’s going to fill Peter up with it. Teeth nips at Peter’s bottom lip until he makes the smallest sound, a little desperate. What? That’s Mr. Stark’s tongue in his mouth.

Tony’s hands slip down under the waistband of Peter’s until he touches hair and Peter writhes, knees clanking together, trying to hide himself even though Tony groans again like he’s found nirvana. His nails rake up the sensitive skin near Peter’s groin. “So soft and beautiful.” Tony bites into the meat of Peter’s shoulder, hips still rutting in a sinful rhythm. “Knew you would be.”

“Are you sure about—ah, about this, Mr, Stark?” Peter tries. His tongue is so thick in his mouth. He can hardly process anything. Beyond Tony is the dingy gray walls of the warehouse, the open space, anyone could walk in and they’d see Tony pinning Peter down with his body. Tony has never looked at him this way; not that Peter hasn’t tried. “You’re…you’re going to hate me later.” He covers his face with his hands, feels the heat on his cheeks.

When he turned seventeen he’d pushed his luck. He touched more, took more. Kissed Tony on the cheek goodbye until he was daring enough to slip, catch just the corner of Tony’s mouth. Peter remembers it, it’s was Monday, rainy, because he’ll never forget the way Tony had looked at him after. Terrified. Disgusted, even. Of Peter. Of Peter kissing him.

Right now, Tony needs more than a sidestep kiss and pat on the shoulder. He needs a hole, something to fuck into, something to take apart piece by piece, and he’s already let Peter know he wasn’t interested in that with him. Peter’s brain is spinning, the reality of the situation started to seep in through the cracks of his shock, and he wonders if he’s being an opportunist by taking Tony’s wandering hands in stride. 

“Oh, darling.” Tony leans in and presses a wet kiss to Peter’s shoulder. “I could never hate you.”

The sound of the zipper fills up the whole room. The space is public, with the open floor and windows and sun streaming down, but it’s quiet, save the police sirens outside. Tens of people, probably, just a flimsy wall away while Tony Stark gets his cock out with a groan. 

It’s thick, uncut, slightly to the left, and nestled in a thick and well-groomed swath of dark hair. Peter knew all that from the videos, the tapes he keeps on his phone for the lonely nights, but that’s just an old image of Tony. Right now, Tony is on his knees above Peter and he grins, circling his cock with his fingers so Peter can watch it twitch. He’s still a bit gray, he looks sick, and his hair is slick against his neck. Peter has always liked that, when it curls there, but Peter can’t look away from the curls around Tony’s cock right now because he’s just a man and his mouth is watering.

“You’re going to be the best thing I’ve ever felt,” Tony says through that wicked grin, eyes dazed — mind far away, probably, since the fight has left him. He leans over, lets his cock drag over Peter’s stomach. Peter feels pre-come in a smooth line and it makes him whimper. “I’ve fucked royalty, the most powerful people in the world, the most beautiful, but I know you’re going to feel the best.”

He kisses Peter then, when Peter opens his mouth and moans at the idea. He brings one thick hand up to Peter’s neck and just holds him, all threat but no pressure, and opens up Peter’s kisses with the flat of his tongue until Peter is weak and loose on the floor. Those fingers pull his mouth down, slip in and feel his tongue slide under the fingertips, and Tony doesn’t have to tell Peter to suck because this has happened in Peter’s head at least twenty five times.

Tony tastes like metal and lotion and salt. He presses on Peter’s tongue until Peter drools around his fingers, grinding his cock into Peter’s hip and rolling his thigh up between Peter’s legs. “Knew you’d melt for me, sugar in the rain, just like that.” 

Peter thinks his eyes might roll back in his head. Is he the one that got caught in the sex pollen nightmare? He feels giddy, almost drunk, and he lets more drool come out of his mouth and slick up Tony’s fingers. He knows where they’re going.

Tony is less single-minded than Peter would have thought, because he’s slow to pull his fingers away and he’s slow to lift up Peter’s leg and he spends an awed moment just looking, which borders on being too much. Peter can feel his ass clench when Tony runs a thumb over the pucker, and his legs tighten around Tony’s hips.

“Just, uh…” Peter wipes his mouth and hides his face in his elbow. “You can start, just…whatever you need.”

Tony presses in gently with the pad of his thumb at the same time he tugs Peter’s arm away from his face, just in time to see Peter’s expression slip into something feral. “Need to see you.” Tony bites into the meat of Peter’s shoulder and laves at it with his tongue. His goatee scrapes across Peter’s skin so good, and Peter curls up until his arms are curling over Tony’s head, hovering, unsure whether to bring him closer or pull him away. “My good boy.”

“Mr. Stark.” Peter presses Tony into his shoulders, another bite, and Tony slips a spit-slick finger inside quick and easy. “Oh, god, I didn’t think—I never thought—”

That’s a lie. Peter thought about it a lot, the way Tony might work him open. Tony’s fingers curl smoothly against Peter’s walls, one to two and then three, a little dry but Peter doesn’t mind when it hurts a little because sometimes soft and sweet feels dull. Sometimes he wants someone to rip him open and make him cry and if Tony is going to do it right now, under threat of death—

“Think about you all the time,” Tony croons heavily against Peter’s skin. He pulls away, purposeful, and Peter blinks. He wonders hysterically if the fog melted away, no more sex magic or whatever it is that’s making Tony want to destroy him, but Tony just draws closer until he can slap his cock around Peter’s swollen mouth. “Get me wet. I’ll make you stop thinking for good.”

Peter groans, an open invitation. This is insane. He shouldn’t enjoy this because Mr. Stark is drugged into wanting him and it’s a huge breach of trust and privacy but Peter scrambled up onto his elbows so Tony can feed him his dick, thick and perfect. He grabs Tony’s hip so hard he thinks there might be bruises but Tony fucks a little harder into his mouth, smooth.

There isn’t a lot of time for sex in his line of work, he’s busy, he’s pining over a man who doesn’t want him, not for real, but Peter isn’t too good to get on his knees in the back of a club and swallow someone down. He knows what he’s doing, throat opening up until the head of Tony’s cock hits the back of his throat. He hums. He loves this. He loves sucking people off, makes his head floaty and easy, and he’s got his eyes closed just to revel in it. He lets drool pool in his mouth again, knows it’s going to make his life easier. 

Tony’s thumb wipes a tear off Peter’s cheek, and it’s only then that Peter opens his eyes and finds his lashes damp, stuck together, watery. “There’s my boy.” It’s so fond. “Don’t cry. You’re doing so well.”

Peter’s hips fuck up into the air and he pulls off, suckling at the head before letting it rest gently on his bottom lip. “I’m good. I’m good, Mr. Stark.” He feels Tony twitch against his mouth. It’s incredible. 

It’s nothing compared to Tony rolling him over on his side, the obscene way Tony hikes up one of Peter’s legs and spits in Peter’s hole and feeds Peter the head of his cock so fast it burns a little, the way Peter kind of likes but won’t admit. It hurts and then his body knows it like this and everything evens out and Tony growls when he thrusts fully into Peter. His skin slaps hard against Peter’s hips, rocking Peter with a surprised cry further across the dusty ground. Tony just smoothes his hand over Peter’s hip, under the knee, and rocks into him. He bites feral at Peter’s neck and shoulders like he’s here to take and claim, like he’s going to want to see the shape of himself on Peter later.

“Oh, Mr. Stark, I’m, ah, oh, please.” Tony brushes up against his prostate and Peter jolts forward, bracing himself with his free hand on the ground to stop from being fucked flat into the floor. “Oh, please. It’s good. It’s good, it’s good.”

Peter isn’t sure Tony can hear anything anymore, but he takes his hand off Peter’s knee and wraps it around Peter’s throat, pulling him back so their bodies are flush and rocking hard and tight into Peter’s body. It’s hard to remember this is just drugs, this is just another day on the job getting fucked by the unrequited love of his life, when Tony watching the way Peter’s eyes roll back so closely. When Tony kisses Peter he tastes like blood but feels like gold, wrapping Peter up tighter. Peter couldn’t leave if he wanted to. He doesn’t want to. He’ll never want to.

“You take me so good, kid,” Tony says against Peter’s jaw, kisses wetly at the skin there. “Thought about this, about opening you up in the lab.”

“Ngh.” Peter is beyond speech, just like Tony promised, but his hand flies back to dig nails into Tony’s hip. His cock aches, dribbling precome onto the dirty floor and the tangle of his ruined clothes. 

“It’s bend you over and slip inside and you’d just—fucking—let me.” He thrusts hard into Peter’s hole, punctuation, and the sound Peter makes is ungodly. “Thought about it when you glued yourself to the wall, just ripping your clothes off—mmm.” A slow roll Peter can feel in his toes. “Find you already open and dripping because I know you fuck yourself sometimes before you come in. FRIDAY can tell.”

Tony isn’t squeezing his throat but Peter can’t breathe.

There are a million and one first hand accounts of Tony Stark’s stroke, but Peter doesn’t think any of them compare to the real thing. On the ground, in the warehouse, while Captain America tries to stop New York’s Finest from throwing open the door and seeing Peter pinned here in the dirt, spread open—

“That’s it,” Tony whispers, gravel. He scratches down Peter’s chest and wraps his hand around Peter’s cock. “You’re so good. Go on. Make a mess. Daddy will clean it up for you.”

It’s deep in Peter’s stomach, rolls up until it burns in his chest and chokes him. His hips cant back, trying to take more of Tony, more more more of something that isn’t here, out here in the open. Everyone knows they’re doing this right now. Fuck. Tony’s suit is still there; FRIDAY is recording all of this, the way Peter shudders and writhes and comes and comes and comes all over Tony’s fist. 

He falls flat on his stomach, Tony’s hand still pumping lightly until Peter is pushing back against Tony’s thrusts just trying to get away from the sensitivity. 

“That’s it, that’s it.” Kisses all over his neck, his throat, his cheeks. “Let me take care of you. Almost there, so good. So perfect.”

There’s no condom. That’s the last thought Peter has, as Tony comes thick and hot in Peter’s ass and grunts, bites one more time. No condom. Very messy. It’s fine, probably, since Tony said he’d clean it up. 

The adrenalin drop hits, empty, and Peter fades away into something deeper than sleep with his cheek pressed into the cold ground and Tony pulling out of his body, wet and sloppy.
